Data Analytics Services

Maillie has transformed the way we audit. Running data analytics tests on extensive amounts of data during the audit planning phase helps provide a better understanding of what is happening in an organization, the areas of greatest risk, and the state of risk management in the entity. Utilizing insights provided by data analysis in this phase of the audit helps shift and refine the focus of the audit early on. Using data analysis in the planning process provides us with a more comprehensive understanding of the scope of the entity.
